什么是tabindex =“-1"?在引导中

问题描述

Bootstrap 3中的tabindex属性有什么用?

尽管他们实际上在所有模态中都使用它们，但其文档中没有提及任何内容.

我只是发现了它的用途，并没有说太多

我发现如果属性不是-1 .

• 按esc键(带有tabindex)后的模式关闭
• 按esc键(不带tabindex)后，模块未关闭

解决方案

这就是为什么在模态<div>上需要tabindex="-1"的原因，以便用户可以访问常见的鼠标和键盘快捷键.希望有帮助.

What's the tabindex attribute in Bootstrap 3 for?

Its documentation doesn't say anything about them although they use them practically in all modals.

I've only find this regarding its use, which doesn't really say much

And I found out I can't press esc to hide a modal if the tabindex attribute is not -1.

• Modal closing after pressing esc key (with tabindex)
• Modal not closing after pressing esc key (without tabindex)

解决方案

This is why you need tabindex="-1" on the modal <div>, so users can access common mouse and keyboard shortcuts. Hope that helps.
